A Miniaturized Transponder Module

The operating mode of the AMVOX2 DBS Transponder represented a daunting challenge in both technical and design terms.
In the first phase, the engineers focused on miniaturising each part of the transponder in order to reduce it to a size that could fit inside a watch case featuring a thickness and diameter ensuring optimal user-friendliness and comfort whilst also meeting the technical and security specifications inherent to the car itself. The end result is a module weighing just a few grams and less than half the size of the same system inside the DBS key.
Nonetheless, miniaturisation was just one of the stages in a global process that led researchers to entirely rethink the geometry and the wiring from a watchmaker's perspective – a high-tech feat that called for 18 months of meticulous engineering work.
